You should be able to find some. I'd think that zucchini and yellow squash are almost grown year round and Fall is coming so people should start growing butternuts or pumpkins growing soon. I'd first try contacting Farm to Kitchen (http://blog.farmtokitchenmiami.com/). Its supposed to be an off shoot business, run by the forager for Michael's Genuine, but they haven't updated their FB page since May, so I don't know if the business is still up.

Roots in the city has squash now. I don't know if their farmers market is open yet but you can see if they can sell you some. Also you can buy a squash plant for HD. It was $5-$6 and about 1' x 1'. They were starting to throw off some flowers. I'm guessing you probably get 1 flower every 3-4 days per plant since its still young. Only thing is when I pushed the leaves around they were some flying bugs hanging around the plant.

never found them here; but if i wanted to try again, i would try homestead; there is a significant (for sofla anyway) Mexican population there; it would not surprise me if some place there sold you some, but call ahead (in Spanish) since it's pretty far and gas is $$$; Good Luck and please share your discoveries!

what is the difference in flavor? or is it just a size thing? I'm sorry i thought they were the same thing lost in translation (since zucchini is a type of squash); in Spanish 'calabasa' can be used to describe any squash (i think) - it doesn't just mean pumpkin, for ex. But if i'm wrong, please school me :)
